'Girls' Script Leaked On The Subway Reveals A BIG Spoiler For Season 4

We're heading west.

When Season 3 of the HBO's "Girls" ended, aspiring scribe Hannah Horvath was deciding whether or not she'd leave Brooklyn, her friends and her boyfriend Adam for a spot at a prestigious writing workshop at the University of Iowa. There was speculation that the show would pick up and plant its roots in the Midwest for Season 4 of filming, but after the University of Iowa made it clear that Lena Dunham and crew were not welcome on campus, we weren't sure if Hannah would ever get out of Greenpoint.

But thanks to a sneaky subway rider and one careless casting director, we have our answer.

According to the New York Post, a casting director affiliated with the show was reading a script for Season 4 while riding the subway and a few crafty commuters were able to get a peak at a few upcoming scenes.

“In one of the scenes, Jessa (Jemima Kirke) and Shoshanna (Zosia Mamet) are FaceTiming with Hannah (Dunham), and they’re in New York while she’s living in Iowa City," one source said.

Apparently, the script was visible to fans who noticed a giant watermark with a casting agent’s name, Tony Behringer, of Central Casting. According to IMDb, Behringer has cast extras in the show before, so it makes sense he'd have a copy of the script.

Central Casting declined The Huffington Post's request for comment.
